I've been loving using these little star sleeves to indicate which cards were actually album pulls for me, as opposed to regular clear sleeves, which I use for cards that I buy or trade for. I like the quality of the sleeves, and the fact that they're PVC- and acid-free.
The only caveat to my love for them is that there is just the smallest bit of yellow tinge to them. It's really only noticeable when you look at the whole stack of sleeves together, or when you're sleeving a card with a cool-toned white in the card, like the background or someone's shirt. The cool-toned white just looks a little warmer due to the yellow tinge of the card, but it's not enough that it bothers me. I know some people are particular about it, though, so I figured I'd mention it. I've included some pictures so you can see the degree to which it changes the color temperature of the card.
I'm definitely going to continue using these for my album pulls because I love how unobtrusive the little star pattern is, while still adding a little sparkle to the cards.
